title: Antidiuretic hormone and osmolality in patients with Ménière's disease.
abstract: Plasma antidiuretic hormone (p-ADH) and plasma osmolality (p-Osm) levels were studied in patients with Ménière's disease. In 147 cases, the p-ADH levels were measured during remission and in the acute phase of the disease. In 100 of 147 cases, the p-Osm levels were determined both in remission and in the acute phase. In remission, the p-ADH and p-Osm levels were higher than the normal limits. In the acute phase, the p-ADH level was higher than that in remission, consistent with previous reports. Moreover, the p-Osm level was unchanged. Although the p-ADH level is regulated by that of p-Osm, the kidney must show an escape phenomenon from antidiuresis. Besides, other factors must increase the amount of p-ADH. Further study is needed to reveal the cause of the rise in p-ADH and p-Osm levels.
